This is the Educational Institution Edition of "Visual Countdown Timer". It has all the great features of the normal version but comes without any Ads or InApp purchases, and is opted into Apple's volume discount for educational institutions. COPPA and GDPR compliant. Is it a battle to get your child to do something quickly? This visual countdown App was designed for my 2 year old son to help him get his reward chart star for getting dressed quickly. Getting him dressed used to take forever with many stalling strategies being deployed. Now he runs upstairs asking for the "Countdown". Watch as the timer runs from green to amber to red, helping the child understand that time is running out. A fun picture is slowly revealed as the time runs down and when the time is up the child is rewarded with an exciting sound and the picture spins. Background image changes to match the time of day, so that your child is given subtle hints as to what time of day the task they are being asked relates to. Choose your own image to reveal from your iPhones photo library to really surprise your child. Endless possible uses: * Getting dressed * Getting out the door (shoes and coats on) * Tidying * Brushing teeth * Sharing toys Turns daily struggles into fun time!
